RE LE ASING ME CHANSM.

To all whom it' may concern:

Be it known that p l, FERDINAND GUN- nonrrr,e1t1zen ot the Dmted States, residing at ortland, county of' Multnomah, and;

State ot Oregon, have invented certain new and useful improvements in Releasing Mechanism, ot' which the following is a specii'ication, reference being had therein to the accompanying drawing.

This invention relates to a releasing mechanism, and is particularly adapted to control the intermittent movement ot power actuated members.

rlhe invention has for an object to provide a spring plate provided with a detent or dog adapted to engage and hold a power` mechanism together' with a controlling wheel having a stop pin by which the detent is forced into holding position together with means for reeasing the parts to permit the desired period of rotation which is automatically stopped.

Other and further objects and advantages of the invention will he hereinafter fully set forth and the novel features thereof defined hy the appended claims.

ln the drawings z-Figure l is an elevation of the invention; Fig. 2 is a section on line 2--2, Fig. l; Figs. 3 and d are diagrams showing different positions of the parts 5 5 is a section showing the parts in Tbottom plan; Fig. 6 is a diagram showing an application oi' the invention.

Like numerals refer to like parts in the several views or the drawing.

The invention is adapted tor application to any character o'r' mechanism, lout for the purpose or illustration, is here shown as assembled in relation to a time mechanism. The releasing mechanism comprises spring plate l@ secured to trame plate i at its end .l2 so that the opposite free end 13 ot the spring plate may move toward and from the frame plate. rlhis end is provided with a dog M which normally hears in contact with the plate 1i. Upon the outer face ot the spring plate a detent vl5 is mounted by pivot 16 and normally held in its raised position by a spring l? which ma)T he integral with the plate, as shown in l, or otherwise applied. The tree end of the detent is provided with a dog l and is extended upward therefrom to form an operating nose 1Q upon one end thereof, having a step lace 20. This nose is adapted to cooperate with a pin 21 carried by the controlling wheel 22, which is pivotally mounted on the frame Specification o Letters Patent.

plate 11 at 23 and extended into the path of the detent. lThis pin 2l engages the nose 19 and lorces the detent away from the pivot Z3 with which it normally contacts, so as to move the tace 2U of the detent into the path of the stop pin 24 carried upon the dist; 25 which is secured upon the power shaft 26 of the operating gear 27.

The pin 24 in the travel of the dish forces the detent downward so that the dog` 18 thereof comes into alinement with the dog 14, as shown in Fig. d, and also into the path ot the fly arm or lever 28 secured to the shat't 2U of the gear 80 and stop the rotation of said ry arm. The disk is provided with the tooth 31 adapted to seat in the spaced reces-ses 32 disposed intermediate ol the curved faces 33 upon the wheel 22. By this means a complete rotation of the disk 25 is required to move the wheel 22 one step forward, and the number oll rotations or the extent oiE movement of the wheel is determined hy the number of spaced recesses therein, which may he varied or arranged to secure the predetermined intervals ot movement desired. rThe fly arm 2S is disposed in a plane parallel to hut heyond the dog 14 when in contact with the plate ll and is not engaged hy said dog until the dog he moved out el." Contact with the trame plate, Figs. 2 and This movement may he secured vby any desired device contacting with the spring plate l0 to move it away from the trame plate 1l. rhe torni here shown comprises a dish 34 mounted in a recess in the trame plate and provided with an extended shalt 36 passing through an aperture in said plate and also through an enlarged. aperture 8.7 in the spring plate so to permit a swing or oscillation ot the shalt tor the purpose ot tilting thcl disl; l a lever action into contact wth the spring l() and thus moving it away from the frame plate, shown in lflig. 5, so that it lies in the path ot the ily lifnile the invention may he used l'or the control ol" any desired mechanism, and is also adapted to he operated by any preferred means, it is here shown as operated hy a time mechanism 38 which is suitably geared to a wheel provided with a pin or projection 40 disposed to travel into contact with the shaft 36 oiE the disl; so as to tilt the latter once in each rotation ol' the wheel. The releasing mechanism in this instance is disposed at the hase ot' the time mechanism to control any desired part or device. This lll() vided With means to engage and shift said de tent, means carried by said disk for operating 1 shaft provided with a holding arm, a spring plate provided with a dog' disposed out of the path of travel of said by said plate and provided vfit posed in the path of travel oE said arm, and means for shifting' said dog laterally of the arm.
